Just, works as you want it to.

Takanobu Watanabe2013年7月25日

GOOD!

Will Patterson2013年7月25日

Works well for the most part, however every time they update it update breaks my userscript (specifically the GM_xmlhttpRequest function) until the browser is restarted. This isn't so bad, but it doesn't give any kind of notification that the browser needs to be restarted, so people using my script think the script is broken and I get flooded with complaints. Please give a notification when an update is occurring that the browser needs to be restarted.

good

This extension gives you control over the web. The craigslist scripts are awesome for searching multiple cities at once, and the features on some of my other favorite sites are just great. A+ App.

AI product read

Userscript manager that allows users to install, manage, edit, and run custom JavaScript userscripts on websites

Enables users to customize and enhance any website by injecting custom scripts that modify page layouts, add/remove features, and automate actions without needing the website owner's permission

User installs Tampermonkey → browses script repositories (Greasy Fork, OpenUserJS, etc.) → installs userscripts → scripts automatically run on matching pages → user manages scripts via dashboard (enable/disable, edit settings, update)

Target users: Power users who want to customize websites / Web developers testing and debugging / Users automating repetitive web tasks / Users who want to modify website UI/UX (ad blocking, dark mode, layout changes) / Privacy-conscious users who want to control what runs on pages

The minified source code makes it difficult to trace exact control flows, but key features (OAuth for cloud sync, no billing/payment code) are clearly identifiable
Cannot fully verify the donation/contribution flow without running the extension, but no payment APIs or gated features were found in source code

Monetization

No paid features detected

Tampermonkey is entirely free with no premium tier, subscription, or gated features. No billing APIs, no Stripe/payment platform integration, no premium feature flags found. The locale files contain 'I contributed already' / 'I don't want to contribute' strings suggesting voluntary donation prompts, but no features are gated behind payment. The 'pro' keyword hits were false positives from locale JSON content.

Confidence: 98
Payment platform: --
Source: AI / High
Login required: No
Reason: Tampermonkey is a local userscript manager that works without any account. The core workflow (install, edit, enable/disable, run userscripts) requires no login. OAuth flows exist for optional cloud sync features (Google Drive, Dropbox, OneDrive, Yandex.Disk) to sync scripts across devices, but these are entirely optional and not part of the core product workflow.
